' (case n) 4 Claims.

' This invention relates to spectacle mountings and. more particularly it has reference to a spectacle'of the semi-rimless type wherein the lenses are detachably held by the resilience of rims which extend alongthe upper edges of the lenses.

One of the objects of my invention is to provide a spectacle of the type described. having improved means for holding the lenses. A further object is to provide such a spectacle embodyin a combined metallic and non-metallic construc- ,,tion. Another; object is to provide a spectacle of the type described which will be neat in ap- -will hereinafter be more fully described and Fig. 1"is a front elevation'of a spectacleembodyin'g-my invention, with the temples-broken away.

Fig. 2 is a top plan view thereof.

Fig. 3 is an enlarged fragmentary view, with the bridge portion in section and with the lens in disassembled relation.

Fig. 4 is a fragmentary view of the bridge portion taken in the direction of the arrows 4-4 on Fig. 3.

Fig. 5 is a view showing the connection of the rim member with the temporal side of the lens.

A preferred embodiment of my invention is disclosed in the drawing wherein It] indicates, generally, a semi-rimless spectacle having the non-metallic bridge portion ll positioned between the lenses l2 and I3. The resilient metallic rim members [4 and i5 extend, respectively, from the nasal sides of the bridge portion H. The nasal end portions of the rim members It and P5 are secured to the non-metallic bridge portion II in any suitable manner such as by embedding them within the plastic material of the non-metallic bridge portion H. The rim members l4 and I5 are positioned rearwardly of the lenses l2 and I3 and extend, respectively, along the top edges and partially down the temporal edges thereof.

The nasal edges of the bridge portion H are provided with grooves it which receive the nasal edges of the lenses which are preferably beveled as shown at IT. The lenses are detachably held in the spactacle mounting by the resilience of the rim members I4 and 15 which. have, respectively, the fingers l8 and I9 which extend forwardly therefrom. The temporal edges of the I lenses are provided with notches 2;! which receive the forwardly extending fingers l8 and I9.

In'order to more securely hold the lenses to the mounting, the nasal edges of the lenses are provided with the notches 2| so that they will receive the projections 22 which are formed'within the grooves It. The projecting ends of the fingers l3 and I9 are bent over as shownat 23 v in Fig. 5 so as to engage the front surfaces of the v k, g

lenses. i g

,rne bridge portionll carries the integrally formed pads 24 which are adapted to engage the nose of the wearrl "The usual endpieces 25 are soldered to; the temporal portions of the rim members It and l5 and pivotally carry the temples 26. f f i From the foregoing, it will be apparent that I am able to attain the objects of my invention and provide a semi-rimless spectacle in which the lenses are detachablyscured by the resilience of the rim-members which extend along the top edges of the lenses. The resilience of the rim members l4 and I5 tends to hold the fingers l8 and iii in the temporal notches on the lenses and also urges the nasal edges of the lenses into cooperative engagement with the grooves it formed on the birdge portion ll. Since the fingers I8 and [9 have their free ends bent over into engagement with the front surfaces of the lenses, it is possible to accommodate lenses of varying thicknesses. A suitable bevel I1 is preferably ground on the nasal sides of the lenses so that they will be in firm coperative engagement with the grooves it. With this construction the lenses are firmly held into the spectacle mounting and yet they may be readily detached therefrom by properly flexing the resilient rim members. While various materials may be utilized in forming my spectacle mounting, the construction lends itself very well to a combined metallic and non-metallic mounting as shown in the drawings.

Various other modifications may, obviously, be made without departing from the spirit of my invention as pointed out in the appended claims.

I claim:

1. A semi-rimless spectacle comprising a nonmetallic bridge portion having grooves in its nasal sides, a pair of lenses positioned respectively with their nasal edges in said grooves, a pair of resilient metallic rim members respectively mounted rearwardly of the lenses, the nasal ends of said rim members being embedded in the bridge portion, said rim members extending along the upper edg s and partially dQW the temporal edges of the lenses, the nasal and temporal edges of the lenses having notches formed therein, projections on the bridge portion and within the grooves, said projections engaging the notches on the nasal edges of the lenses, and fingers projecting forwardly from the temporal portions of the rim members, said fingers andtprojectionsi being held in'the notches on the temporal-and nasal edges of the lenses by the resilience of the rim members whereby the lenses are detachably held in the spectacle.
